Possible enhancement? Adding HashMap::entry like methods

[zelenij]

Is it possible to enhance the generated code, so that it also produces methods like entry in HashMap? This is to work around the issue as in this SO post:

So if the original struct has a hashed field id, then the macro would generate both get_by_id and entry_by_id.
